MDF or Plywood for best sound in Hi-Fi rack ?


I need to make to more shelves for my rack. One for my CD and one for the preamp. I use Vibrapods under each unit. Is MDF or plywood better for sound quality or vibration control? Thanks

MDF will be better than plywood. If you want to spend more you can find a Lumber Liquidators and get maple butcher block. I believe it comes in 8' and 12' lengths by 24" wide.
Can you find maple butcher blocks,maybe at T J Maxx?They come in several different sizes and are relatively cheap.
